A

Osteogenic cells

40
Q

What does it mean to say bones have a dynamic nature

A

New tissue is constantly formed

41
Q

Osteoblasts vs. osteoclasts

A

Blasts - Form new bone
Clasts - Reshaping bone

42
Q

Compact vs. spongy bone

Compact is dencse
Spongy has spours and is not dense

43
Q

Where is the compact bone found in the long bone?

A

In the diaphysis

44
Q

Describe an osteon

A

Microscopic structural unit of compact bone

45
Q

What is un the haversian canal of an osteon

A

Blood vessels, nerves, and lymphatic vessels

46
Q

Describe how the Volkmanns canal branches off the Haversian canal

A

Extends to the periosteum and endosteum

47
Q

Describe the network system that is created by the canaliculi. What function does it serve?

A

Connects with canaliculi or other lacunae and eventually with the haversian canal.

48
Q

What function does the canaliculi serve?

A

Allows nutrietns to be transported to osteosteum and wastes removes them.

49
Q

The trabeculae of spongy bone may appear random,but describe the pattern in which they form and why.

A

Forms along lines of stress to provide strength to the bones

50
Q

How do the spaces inthe spnogy bone provide balance to the bones as a whole?

A

Makes bones lighter so moves can move closer

51

The head, neck, trunk, skull, hybroid bone, vertevral column, ribcage, and sternum

52
Q

Appendicular contains……
